I'm not a fan of making clients include paths have references to our src
directory.  However, I understand not wanting to add headers to our include
directory that we don't want people referencing directly.  It just doesn't seem
like the solution should be making them include our src/ports directory.  Is
there a strong argument against make the atomic and mutex headers part of our
include dir?

Done.
